Or instead of using a calculator you can just look at the images.
Because experiencing a diffraction limited pic is not a black and white
thing. The issue would be how much diffraction is going to make a difference
on your shots. Not the odd idea that any diffraction at all makes it a
reject.  Another ongoing LUG Myth. And just as nutty as most of them.
You reach a trade off between the DOF you are getting and the loss of
contrast from diffraction. And the idea that such a loss of contrast can be
put back into the image in Photoshop or Lightroom in about a second and a
half.
